For an integer k ≥ 2, let
be the k-generalized Fibonacci
sequence that starts n with 0,..., 0, 1, 1 (k terms)
and each term
afterwards is the sum of k preceding terms. In this paper, we find all
the k-generalized Fibonacci numbers that are Leonardo numbers. More
explicitly, we solve the Diophantine equation
Fn(k) = Lem
in positive integers n, k, m with k ≥ 2.
